Abstract: 1,127,527. Coated sheet material. REVERTEX, Ltd. 30 March, 1967 [6 April, 1966], No. 15381/66. Heading B2E. A textile fabric material e.g. a tufted carpet or a knitted pile fabric, is backed by a process comprising the steps of compounding a rubber latex mix from natural rubber latex, synthetic rubber latex, or a blend of such latices, a mineral filler, and a gelling control agent comprising zinc oxide, adding a gelling agent to the mix, applying the mix to one side of a textile fabric using a stationary applicator shaped to provide a pattern in the wet mix, the viscosity of the mix being such as to substantially retain the pattern therein, and then subjecting the backed fabric to heat to gel and dry the mix in the pattern. The applicator may be a comb, patterned bar, or patterned non-rotary cylinder. The fabric may be first backed by an amount of the mix just sufficient to cover the fabric applied by a straight doctor blade set just in front of the applicator relative to the direction of movement of the fabric in relation to the applicator. The mix may have a visocity within the range of 12 to 16 poises when measured in a Ferranti viscometer, model VH, Spindle A, Speed 3 at 18‹C. and may be applied at a rate not less than 500 g. per square metre.

[Class 71] [See also Group XL] For evacuating gases from an electrical discharge device 1 having a filling of metal vapour, a receptacle 5 containing an adsorbing or absorbing medium is connected thereto through a high-vacuum pump 7. The medium may consist of alkalies, sulphuric acid, carbon or phosphorus pentoxide. Cooling ribs 11, 12 are provided for the diffusion pump and for the connecting pipe 3 which is inclined to facilitate the return of condensate to the device. A seal comprising a glass filter 9 and mercury 10 is provided in the connecting pipe 8 and prevents the return of gas to the device if the pump fails. When the device is heated to facilitate the initial exhaustion thereof by an auxiliary pump, the medium in 5 is also heated to prevent it absorbing gases. The medium may be regenerated by heating and connecting the receptacle to a pump.

Title: Josamycin derivatives
Inventor: OSONO TAKASHI

Filed: 1969-03-25
Abstract: 1,259,682. Acyl derivatives of the antibiotic Josamycin. YAMANOUCHI PHARMACEUTICAL CO. Ltd. 25 March, 1969 [29 March, 1968 (2)], No. 15654/69. Heading C2A. Novel acyl derivatives of the antibiotic Josamycin, wherein one or both of the secondary hydroxyl groups are acylated, are prepared by treating the antibiotic with a carboxylic acid or an acylating derivative thereof (e.g. the anhydride or halide), (a) using one equivalent of acylating agent to give acyl-josamycin-1; or (b) using two or more equivalents of the agent under basic reaction conditions to give diacyljosamycin; and optionally (c) hydrolysing diacyl-josamycin to give acyl-josamycin-2. The acyl derivatives 1 and 2 differ in the position of - the acylated hydroxyl group, as shown by the respective melting points of the acetyl derivatives, 182-183‹ C. and 128-131‹ C. The acylating groups may be acetyl, propionyl, butyryl, benzoyl, or isovaleroyl. Reaction (a) is preferably carried out in an organic solvent (e.g. lower alcohols, ethyl acetate or acetone) with heating; an acid acceptor, e.g. NaHCO 3 , may be present when the acid halide is used as the acylating agent. The di-acylation (b) is preferably carried out using the acylating acid anhydride as a reaction medium, with the addition of an organic base such as pyridine or quinoline. Hydrolysis (c) may be effected by heating the diacyl product in aqueous-alcohol, -acetone, -methylethylketone, -dioxane or -dimethylformamide, preferably with the addition of an inorganic base or acid. If the products do not crystallize out spontaneously from the reaction mixture, they may be recovered by adding a non-solvent and/or concentrating the mixture. The acyl derivatives lack the bitter taste of josamycin while retaining its antibiotic activity. Pharmaceutical compositions comprise a mono- or di-acyl derivative of the antibiotic josamycin together with an acceptable carrier; they are in forms for oral administration, such as tablets, powders, granules, syrups, chewable tablets or capsules.

Title: Improvements in fuel injection devices
IPC: F02M59/00

Abstract: 861,753. Fuel injection pumps. BESSIERE, P. E. May 21, 1957 [May 24, 1956], No. 16129/57. Class 102(1). A fuel injection pump comprises a plunger 1 reciprocating in a cylinder 2 having an inlet port 3 and outlet passage 4 leading to an injector, the piston being driven in accordance with the engine speed such that its speed increases during its compression stroke. A piston member 8 is provided with an axial passage 5 opening into a chamber 6 and passageway 7. The outlet of the passage 5 may be adjustable. In operation after the piston 1 has closed the inlet port 3 fuel leaks through the passage 5 until the pressure in the cylinder 2 increases to move the piston member 8 against a spring force 9 to close the passage 5 from the chamber 6. The pressure in the cylinder 2 then rises quickly until it reaches a value to open a non-return valve in the outlet passage 4 and flow to the injector. As the speed of the engine increases so will the passage 5 be closed sooner thus providing an advance in timing with increased engine speed. In a modified form the lower end of the piston member 8 may close the outlet passage 4 in its lower most position. In a further modifica tion the spring 9 may be replaced by a magnetic locking device as described in Specification 841,202. In another modification the piston 8 is replaced by a piston member having a tapered lowered end such that once this member has started to move it offers an increased area to fuel pressure acting on it. An adjustable abutment 13 is provided to limit the movement of the piston 8 and by suitable adjustment the piston 8 may be utilised to decrease the volume of fuel injected in each cycle by being displaced. sufficiently to provide a space to be filled by the fuel from the cylinder 2. The leak device may be arranged in the outlet passage 4 or may be provided in a space filled with liquid but separated from the cylinder 2 by a free piston or diaphragm.
